About A4Fitness

A4 Fitness is now the most complete Fitness/CrossFit and Martial Arts gym in Los Angeles after our purchase of AMMS. I hope all our friends and clients will be happy to know, we have completed the adaptation of "Academy of Mixed Martial Science" into A4 Fitness. We specialize in Crossfit, Personal training, Boxing, Muay Thai, Jiu Jitsu, Yoga and MMA. Whether you want to learn to throw a punch, do a pull up, clean & jerk your bodyweight, walk on your hands, run fast, jump high, eat healthy, eliminate pain from old injuries, take a deep breath during a yoga pose, live longer or simply look hot in a bikini, we will guide you at A4 Fitness in the most fun and supportive way possible.

What differentiates us

We have the most experienced trainers and because we cap our class sizes and provide assistant coaches, we have the best client to trainer ratio in Los Angeles.

How we were trained

All of our trainers are highly experienced and hold certifications with ACE, NASM, CrossFit, USA Boxing and USA Weightlifting.

Why we love what we do

A4 Fitness changes lives every day of the week and our members won't stop reminding us how much they love it. We sleep well at night knowing we are making people healthier, happier and more fit than they have ever been in their lives.
